* Operation steps

1. Let oxygen generator power cord plugs access mains.

2. Turn on circuit breaker switch of the oxygen generator, and green LED indicator,

LCD screen, red LED indicator for low oxygen will be on.

3, Open the knob of flow meter.

4. Turn knob left to "ON" , oxygen generator began to work.

5' After the system is on and empty valve start for 10 seconds which guarantee the

compressor start (the valve for normally open valve)

6. Oxygen generator's outlet pressure after 60 seconds: JAY-10-4.0. JAy-15-4.0.

JAY-20-4.0 above 0. 35Mpa.

7. after 3 minutes of operation, flow meter should be adjusted to required flow. but not

greater than the standard flow value. Oxygen output pressure can be adjusted by the

pressure regulating valve, but not more than the rated pressure value(when>0.45 Mpa

will stop).

8. oxygen purity should be above 90% after operating 10 minutes.

9' lf not continuously be used, please shut off the power (disconnect oxygen generator

in circuit breaker switch) and unplugged.

10. Oxygen purity alarm function: after ten minutes it will reach the normal.

When oxygen purity < 84o/o, error+ 2o/o, "L.o2" red LED light, show low oxygen purity.

When oxygen purity 2 84o/o, error+ 2o/o, "H.O2', blue LED light.

11' lf starting fifteen minutes and the low oxygen concentration light "L.O2" still red,

the system operation is unnormal.

Now check if position of the pressure reducing valve for oxygen sensors is normal,

because too much flow in the oxygen sensor can make output purity of oxygen

generator insufficient. By adjusting the pressure reducing valve (oxygen sensor with)

make its flow meet the requirements, or close concentration light of the valve also can't

make blue LED light,: the oxygen sensor should be checked for adjustment with

pressure reducing valve, with reference to the ((maintenance instructions) in item six .

12. Drain valve starts for 5 seconds according to interval setting time (note: discharge

of water should be properly handled, such as drainage or container collection).

13. when Turning off (rotary switch to "oFF"), axial fan, and cooling drying device

stop work. after 60 seconds

* Maintenance instructions'1 ' Please cut off the power supply, the external casing use clean soft wet towel touchsa few cleaner, wipe external casing everywhere, then dry towel cleaning, 1 - 2 times amonth.

2. clean primary filter is an important step of the dairy maintenance(see cleaning requirements table)Methods: the case should be cleaned with cleanser Thoroughly andthen risen with dry cloth twice every month.

3. Change second filter(see cleaning requirements table)3.1 JAY-10-4.0, JAY-20-4.0 Model (change filter cotton)Open the oxygen generator side door, open the secondaryfilter remove filter cotton, the most outside a piece of change(figure 2), on the inside, make originally the second piece in thefirst place,and rotation use.

3.2 JAY-15-4.0 model:Open the oxygen generator side door and checkif the secondary filter became black, if yes, changethe new filter.

4. Clean third inlet filter(see cleaning requirements table)4.1 JAY-10-4.0. JAY-20-4.0 Model (change the filter cotton),Open the oxygen generator side door, Unplug the silicone rubbertube on the top of third filter, turn on the third filter and change thefilter cotton. at the same time clean filter's cavity.

4.2 JAY-15-4.0 model (change filter element),open the oxygen generator left side door, upload compressorlnternal case side board, unscrew the third filter fastening screw,open the black case, replace the internal filter core, and at thesame time clean filter cavity.

5. Replace fourth filter

Open the oxygen generator side door, ln the panel nearthe oxygen outlet position, check the fourth firter's color, if colorchanged,unscrew filter and change the element.

6, Use reducing valve check oxygen sensor

Reducing valve is used to check whether oxygen purity is normal.othenryise ,Oxygen sensor is supplied more oxygen, it willlead to loss of pressure of the oxygen ouflet, flow reducing,because too much oxygen to oxygen sensor will reducing thepurity and pressure of the outlet. The best way to check howmuch amount of oxygen to the oxygen sensor is to connect atube to the oxygen sensor output and put this tube to the water

(as shown in picture) and if one bubble will appear in the waterevery a second, it will be oK. lf more continuous bubbles appears,the reducing valve should be adjusted to its best condition7. CompressorCompressor positioning is made of a positioning screw, damping spring and statorcomposition, lt can show clear positioning screw and bottom friction sound whenhappened offset, external forces need to put to compressor in the right position.Compressor need maintain every year, blowing the dust on the surface and checkwiring.
